After looking at the code, the most plausible explanation seems to be
that the index on pg_largeobject is broken. Try reindexing
pg_largeobject. (You'l likely need to do this in single-user mode;
read the REINDEX man page carefully.)
7.2.1 is by no means current, btw. I recommend an update to 7.2.4 at
least, or 7.3 if you can.
